Ask a PT Response: "My first recommendation would be to utilze a bra or sports bra which will provide adequate support. This will assist with reducing some of the stresses on your back. Core strengthening and core stabilization exercises are usually recommended for this problem. With my patients, I like them to perform exercises on the gym ball and on the mat. You can see some examples of these exercises on our exercise videos page. http://www.cyberpt.com/cptvidlist.asp - http://www.cyberpt.com/cptvidlist.asp . Another article which has some exercise samples can be found here: http://www.sheknows.com/health-and-wellness/articles/811794/back-exercises-to-support-your-breasts - http://www.sheknows.com/health-and-wellness/articles/811794/back-exercises-to-support-your-breasts . Without evaluating you I am unable to recommend specific exercises. Other exercise programs which patients have also found to be helpful include Yoga and Pilates. If you are able to, it would probably be best to work with a physical therapist so that he or she can evaluate you and develop a plan of care specific to your needs. I wish you the best of luck. "
